<strong>Instructions</strong> for Completing Part II of EPA Form R<br />

1.3 Generic <strong>Chemical</strong> Name<br />

Complete Section 1.3 only if you are claiming the specific<br />

EPCRA section 313 chemical identity of the EPCRA section<br />

313 chemical as a trade secret <strong>and</strong> have marked the trade secret<br />

block in Part I, Section 2.1 on page 1 of Form R. Enter a<br />

generic chemical name that is descriptive of the chemical<br />

structure. You should limit the generic name to seventy<br />

characters (e.g., numbers, letters, spaces, punctuation) or less.<br />

Do not enter mixture names in Section 1.3; see Section 2<br />

below.<br />

In-house plant codes <strong>and</strong> other substitute names that are not<br />

structurally descriptive of the EPCRA section 313 chemical<br />

identity being withheld as a trade secret are not acceptable as a<br />

generic name. The generic name must appear on both sanitized<br />

<strong>and</strong> unsanitized Form Rs, <strong>and</strong> the name must be the same as<br />

that used on your substantiation forms.<br />

1.4 Distribution of Each Member of the Dioxin <strong>and</strong><br />

Dioxin-like Compounds Category<br />

Report a distribution of the chemicals included in the dioxin<br />

<strong>and</strong> dioxin-like compounds category. Such distribution shall<br />

either represent the distribution of the total quantity of dioxin<br />

<strong>and</strong> dioxin-like compounds released to all media from your<br />

facility; or your facility's one best media-specific distribution.<br />

When reporting dioxin <strong>and</strong> dioxin-like compounds, if there are<br />

any numbers in boxes 1-17, then every field must be filled in<br />

with either 0 or some number between 0.01 <strong>and</strong> 100.<br />

Distribution should be reported in percentages <strong>and</strong> the total<br />

should equal 100%. If you do not have speciation data<br />

available, you should indicate NA. If you are not reporting for<br />

dioxin <strong>and</strong> dioxin-like compounds, leave the entire section<br />

blank.<br />

You should not report the quantity of dioxin <strong>and</strong> dioxin-like<br />

compounds released or otherwise managed as waste in Section<br />

1.4. Quantities released or otherwise managed as waste must<br />

be reported in Sections 5, 6 <strong>and</strong> 8.<br />

There are 17 individual chemicals listed in the dioxin <strong>and</strong><br />

dioxin-like compounds category. Each of these chemicals are<br />

assigned a number from 1 to 17. These numbers correspond to<br />

the boxes in Section 1.4. The individual chemicals in the<br />

dioxin <strong>and</strong> dioxin-like compounds category <strong>and</strong> their number<br />

are in the matrix below:<br />

6 60851–34–5 2,3,4,6,7,8-Hexachlorodibenzofuran<br />

7 39227–28–6 1,2,3,4,7,8-Hexachlorodibenzo- p-dioxin<br />

8 57653–85–7 1,2,3,6,7,8-Hexachlorodibenzo- p-dioxin<br />

9 19408–74–3 1,2,3,7,8,9-Hexachlorodibenzo- p-dioxin<br />

10 35822–46–9 1,2,3,4,6,7,8-Heptachlorodibenzo- p-<br />

dioxin<br />

11 39001–02–0 1,2,3,4,6,7,8,9-Octachlorodibenzofuran<br />

12 03268–87–9 1,2,3,4,6,7,8,9-Octachlorodibenzo- p-<br />

dioxin<br />

13 57117–41–6 1,2,3,7,8-Pentachlorodibenzofuran<br />

14 57117–31–4 2,3,4,7,8-Pentachlorodibenzofuran<br />

15 40321–76–4 1,2,3,7,8-Pentachlorodibenzo- p-dioxin<br />

16 51207–31–9 2,3,7,8-Tetrachlorodibenzofuran<br />

17 01746–01–6 2,3,7,8-Tetrachlorodibenzo- p-dioxin<br />

Section 2. Mixture Component Identity<br />

Do not complete this section if you have completed Section 1 of<br />

Part II. Report the generic name provided to you by your<br />

supplier in this section if your supplier is claiming the chemical<br />

identity proprietary or trade secret. Do not answer “yes” in Part<br />

I, Section 2.1 on page 1 of the form if you complete this section.<br />

You do not need to supply trade secret substantiation forms for<br />

this EPCRA section 313 chemical because it is your supplier<br />

who is claiming the chemical identity a trade secret.<br />

Example 10: Mixture Containing Unidentified<br />

EPCRA Section 313 <strong>Chemical</strong><br />

Your facility uses 20,000 pounds of a solvent that your<br />

supplier has told you contains 80% “chlorinated aromatic,”<br />

their generic name for a non-PBT EPCRA section 313<br />

chemical subject to reporting under EPCRA section 313.<br />

You, therefore, have used 16,000 pounds of some EPCRA<br />

section 313 chemical <strong>and</strong> that exceeds the “otherwise use”<br />

threshold for a non-PBT chemical. You would file a Form<br />

R <strong>and</strong> enter the name “chlorinated aromatic” in the space<br />

provided in Part II, Section 2.<br />

1 67562–39–4 1,2,3,4,6,7,8-Heptachlorodibenzofuran<br />

2 55673–89–7 1,2,3,4,7,8,9-Heptachlorodibenzofuran<br />

3 70648–26–9 1,2,3,4,7,8-Hexachlorodibenzofuran<br />

2.1 Generic <strong>Chemical</strong> Name Provided by Supplier<br />

Enter the generic chemical name in this section only if the<br />

following three conditions apply:<br />

4 57117–44–9 1,2,3,6,7,8-Hexachlorodibenzofuran<br />

5 72918–21–9 1,2,3,7,8,9-Hexachlorodibenzofuran<br />
